Computer notification that phone battery was almost dead???

Ok... I just got a Windows (10) notification in the action message side panel on my computer telling me my Note 4 battery was almost dead...
This has never happened before... The phone was not even plugged into the computer.... Its a desktop and has no bluetooth or wifi... How and the hell did it do that!!!

Do you have Cortana installed on your phone? It syncs messages across the internet, such as missed calls, or low battery status.

Holy cow.... yep... just installed it last week.. Thanks!!! It freaked me out because I couldn't figure out how it could know that without being connected to computer and it hadn't done it in the 3 years I have had the phone
